Abstract
1305279 Photo-electric analysis ESSO RESEARCH & ENG CO 23 March 1970 [8 May 1969] 13812/70 Heading G1A [Also in Division B1] Fluid solids from catalyst regenerator standpipe 22 are analysed by a method which comprises (Fig. 1), intermittently obtaining a sample of the solids by opening valves 20, 16, 14, valve 18 remaining closed transferring the sample to a defluidizing zone 24, defluidizing the sample by settling solids and venting the gas through line 17, transferring the sample from the defluidizing zone to a sample collecting zone formed by depression 35 in slide 34, transferring the sample from the sample collecting zone 32 to an analysing zone 36, and analysing the sample for example by light reflectance measurements. Light emanating from source 50, Fig. 4, at 45 angle is reflected from the sample into zone 52 which includes a photo-cell and amplifier (not shown). The voltage signal generated is 3ent by line 55 to rewinding or indicating means 7 62 which is calibrated in terms of percent carbon. Cap 54 allows removal of any solids accumulating in analysis chamber 36. Zones 32 and 36 are isolated from one another as by sealing means 40 while the sample is being transferred from the defluidizing zone to slide 34. Slide 84 may be an extension of piston rod 42 and is moved between chambers 32, 36 by injection of oil into cylinder 44 through lines 39 or 47. After analysis the sample is returned to zone on slide 34 then removed from depression 35 and blown to waste through line 21 by means of purge gas entering by 58. There are references to determination of percent carbon on a cracking catalyst and of per cent metallization (i.e. % metallic Fe/ total Fe) in Iron-ore reduction processes.
